Error occured while converting png to webp

[inajaf]

When trying to convert png images to webp error occured: Warning: imagecreatefrompng(): gd-png: libpng warning: Interlace handling should be turned on when using png_read_image and for some png filles the following error occured: imagecreatefrompng(): gd-png: libpng warning: iCCP: known incorrect sRGB profile

Here is my class: which scans uploads folder and subfolder for image files for converting to webp:

Have same issue while using one of module using this repository. Any idea how Warning: imagecreatefrompng(): gd-png: libpng warning: Interlace handling should be turned on when using png_read_image should be handled?

I used Imagick instead of Gd converter. Convertation is working but very slow.

this fix the issue with gd on Windows error_reporting(0);

It seems warnings could be suppressed using @ : $image = @imagecreatefrompng($this->source);
